to which it appertains to make and use the same.

The object of the invention is to provide a closure for joints, particularly where it is desired 4to make anair tight joint between two surfaces in a short space of time, and allowing a quick release of the two surfaces when desired, as for example in the case of torpedo tube breech doors, entrance scuttles, etc. in submarine boats.

The particular nature and mode of operation of the invention will be understood from the following description and the accompanying drawings.

In the drawings Figure 1 is a central vertical section of-a structure embodying our improved closure or gasket, and Fig. 2 is a fragmentary plan partlybroken away of aortion of the structure in which the gasket 1s seated.

`In the drawings a represents a receptacle of any character which it isdesired to vsurround with a closure effective to revent the escape of gas under pressure. his receptacle is sup orted in a frame b which 1s adapted to be quickly, and rather loosely, attached to a base c by the bolts d.. It would be impossible to secure the desired closure between two such parts by the use of the bolts alone, and to afford the desired closure we provide the structure shown com prising 'a gasket c'of rubber or the like, fitted within a dovetail annular recess in the base c and surrounding the ed e of the receptacle a.

recess is a pressure pipe g extendin from a pressure reservoir k containing a nid un'- A small space f, in icated as an annular Vrecess semi-cylindrical in cross-'sec- ,der pressure, said pressure pipe being controlled by cock z' and containin the relief cock k for permittingy the ready ischarge of the pressure.

It will be understood that though we have in the drawin s shown an annular recess of a dove-tail orm, to contain the gasket e, the recess will in general be made to follow the outline of the opening, and may ,be of any form in cross-section adapted to retain the rubber ring, though the dove-tail form is one which is. easily machined and is cii'ect-y ive in practice.

From the foregoing description it will be understood that the structure employed is one in which the two separable parts may readily be attached to` one' another by the bolts' d, and that when they have been so attached the closure may be attained by admitting pressure from the tank h abora-f the gasket c to force the rubber against theY face lof thc attached part b and against the sides of the containing groove, thereby making a complete closure against the pressure contained in the receptacle a.

lVhile we have shown bolts to illustrate a means of holding the two members together, it will be readily understood that any means for" holding the surfaces together can be substituted, such as clamping devioes ,'in terrupted threads, or interru ted Bange joints, whichcan be readily re eased by a single movement.

That we claim is:

The combination with two separable inembers attached together, of a closure for the joint between said members comprising a gasket seated in a groove in one of said members, a reservoir containingafluid under pressure, and connections from the reservoir to a space in the groove behind the asket, whereby the pressure may be applied ehind the gasket to effect the closure.

In testimony whereof we aix oursignatures, in presence of two witnesses.
